In order to use dynamic DNS in our installation, we used to pass a workstations hostname with the "-h hostname" option to dhcpcd in the 5.2 "ifup" script. pump does not appear to take that as a valid option. This is critical, as the hostname argument gets sent with the dhcp request, and our dhcp server updates DNS with said received name. Please advise... and this is a pretty critical thing to simply replace on an upgrade... Not too cool... please don't ever become evil.
fixed in pump-0.6.7-1, available in the Errata...
